网站制作完成后为了wordpress 改地址

效果图

定义一个连接桩公共方法

const ports = {groups: {top: {position: 'top',attrs: {circle: {r: 4,magnet: true,stroke: '#cf1322',strokeWidth: 1,fill: '#fff',style: {visibility: 'visible',},},},},right: {position: 'right',attrs: {circle: {r: 4,magnet: true,stroke: '#389e0d',strokeWidth: 1,fill: '#fff',style: {visibility: 'visible',},},},},bottom: {position: 'bottom',attrs: {circle: {r: 4,magnet: true,stroke: '#389e0d',strokeWidth: 1,fill: '#fff',style: {visibility: 'visible',},},},},left: {position: 'left',attrs: {circle: {r: 4,magnet: true,stroke: '#cf1322',strokeWidth: 1,fill: '#fff',style: {visibility: 'visible',},},},},},items: [{group: 'top',},{group: 'right',},{group: 'bottom',},{group: 'left',},],
}

注册图形节点

Shape.HTML.register({shape: 'html',width: 70,height: 36,effect: ['data'],html(cell) {const { label, props } = cell.getData()const div = document.createElement('div')div.style.width = 70const titleDiv = document.createElement('div')titleDiv.style.width = '70px'titleDiv.style.height = '36px'titleDiv.style.background = '#eb2f96'titleDiv.style.color = 'white'titleDiv.style.fontSize = '14px'titleDiv.style.textAlign = 'center'titleDiv.style.lineHeight = '36px'titleDiv.style.boxSizing = 'border-box'titleDiv.style.fontSize = '12px'titleDiv.style.borderRadius = '6px'titleDiv.style.whiteSpace = 'nowrap'titleDiv.style.overflow = 'hidden'titleDiv.style.textOverflow = 'ellipsis'titleDiv.setAttribute('title', label)titleDiv.textContent = labeldiv.append(titleDiv)return div},ports: { ...ports,items: [{group: 'left'},{group: 'right'}]},})

1. effect 是当前节点的 prop 数组，当 effect 包含的 prop 有变动时，会重新执行 html 方法，返回新的 dom，更新节点内容；
2. ports 是此节点的连接桩；此节点只用到了左右两个连接桩；

创建html节点

const r2 = this.graph.createNode({shape: 'html',data: {props:{desc: ''},label: '自定义html',},
})

1. shape 要和注册节点里的名称一致；

动态更新节点内容

let cell = this.graph.getCellById(id)
cell.prop('data/label', '文字')
cell.prop('data/props/voice', 'desc')

• id 是要更改内容的cell的id；
